Job Triggers and JobStatus Enum not working as expected

Did something change with the Job object that is sent on triggers?

I had a conditional, similar to the following, that suddenly stopped working: ($Job.Status -eq 'Completed')? 'True' : 'False')

I found out that it seems to have to do with the JobStatus enum becoming Deserialized.PowershellUniversal.JobStatus, if I instead use the integer value of the Enum, it works fine.

A test trigger script that causes the issue looks like this:


    Job Status: $($Job.Status)
    Job Status TypeNames: $($Job.Status.psobject.Typenames)
    Job Status -eq 'Completed': $($Job.Status -eq 'Completed')
    Job Status -eq 2: $($Job.Status -eq 2)
    (Direct Cast to [PowershellUniversal.JobStatus]) Job Status -eq 'Completed': $([PowerShellUniversal.JobStatus]$Job.Status -eq 'Completed')
    Switch Job Status: $(switch ($Job.Status) {
        'Completed' { 'Branched on Completed' }
        Default {'Default Branch'}

Output is:

[information]     Job Status: 2
    Job Status TypeNames: Deserialized.PowerShellUniversal.JobStatus Deserialized.System.Enum Deserialized.System.ValueType Deserialized.System.Object
    Job Status -eq 'Completed': False
    Job Status -eq 2: True
    (Direct Cast to [PowershellUniversal.JobStatus]) Job Status -eq 'Completed': True
    Switch Job Status: Default Branch 

I did fix it by direct casting, but it seems to have happened after the update to 3.7 (maybe 3.7.7 specifically?)

Product: PowerShell Universal
Version: 3.7.7

This may have been because we were originally only serializing a single depth for the metadata for triggers. If I had to venture a guess, the JobStatus was being serialized to a string at the depth of 1 but now that we’ve increased the depth, it is not becoming an enum.

I have to admit, I’m a bit surprised you can’t compare with a string as that seems like a regular PowerShell thing. The reason this change was made was because some of the trigger meta data objects were more complex than we were serializing for.

Some helpful Powershell gurus pointed out that serializing and deserializing converts enums into a plain object, so basically it is converted into the base type (integer), it just also contains metadata so that Powershell typenames are preserved.

Basically I should just use the enum in my equality to maintain readability and functionality

$Job.Status -eq [PowerShellUniversal.JobStatus]::Completed
